The importance of aviation safety has been emphasized recently due to the development of aviation industry. Despite the efforts of each country and the improvement of screening equipment, screening tasks are still difficult and detection failures are frequent. The purpose of this study was to examine the effect of feedback on improving signal detection performance applying a Simulated Baggage Screening Program(SBSP) for improving aviation safety. SBSP consists of three parts: image combination, option setting and experiment. The experimental images were color-coded to reflect the items' transmittance of the x-rays and could be combined as researchers' need. In the option, the researcher could set up the information, incentive, and comments needed for training to be delivered on a number of tasks and times. Experiment was conducted using SBSP and participant's performance information (hit, missed, false alarms, correct rejection, reaction time, etc.) was automatically calculated and stored. A total of 50 participants participated and each participant was randomly assigned to feedback and non-feedback group. Participants performed a total of 200 tasks and 20(10%) contained target object(gun and knife). The results showed that when the feedback was provided, the hit, correct rejection ratio and d′ were increased, however, the false alarms and miss decreased. However, there was no significant difference in response criteria(${\beta}$). In addition, implications, limitations of this study and future research were discussed.

2015 개정 교육과정에 따르면, 초등학교 SW교육은 실과 교과에서 17시간이라는 제한된 시간을 할애하고 있어, SW교육의 목적을 달성하는 데 한계가 있다. 따라서 본 연구에서는 초등학교 SW 교육과정에 대한 표준 모델을 제시하였다. 이를 위해 국내외 SW 교육과정을 분석한 후 SW 내용 체계를 소프트웨어, 컴퓨터 시스템, 융합활동 등 3개 영역으로 구분하고, 하위 영역을 10개 영역으로 구분하였다. 또한, SW 교육 내용을 학년의 구분없이 학습할 수 있도록 무지개 색을 이용하여 7단계로 구분하였다. 향후 제안된 교육과정 모델을 토대로 교재와 교구를 개발하여 보급한다면 학교 현장의 SW교육 발전에 기여할 것이다.
